Engine Oil Pressure Gauge - GMC Chevrolet Silverado 2500HD 2021 Owner's Manual

Here are four things that some owners ask
about. None of these show a problem with
the fuel gauge:
At the service station, the fuel pump
shuts off before the gauge reads full.
It takes a little more or less fuel to fill up
than the gauge indicated. For example,
the gauge may have indicated the tank
was half full, but it actually took a little
more or less than half the tank's capacity
to fill the tank.
The gauge moves a little while turning a
corner or speeding up.
The gauge takes a few seconds to
stabilize after the ignition is turned on,
and goes back to empty when the
ignition is turned off.

the engine speed or load varies. This is
normal. If the oil pressure warning light or
